Some questions about CROMU_00093

[xiajia95]

Hello，
I want to debug the corpus "CROMU_00093", when I run 'make', it occurs an error:

Traceback (most recent call last):
File "/usr/bin/generate-polls", line 149, in
main()
File "/usr/bin/generate-polls", line 141, in main
graph.walk()
File "/usr/lib/pymodules/python2.7/generator/graph.py", line 204, in walk
response = node()
File "poller/for-release/machine.py", line 216, in mailsend
self.init_prng()
File "poller/for-release/machine.py", line 36, in init_prng
self.random_state.append(unpack("<Q", self.magic_page[i8: i8 + 8])[0])
AttributeError: 'MorrisGenerator' object has no attribute 'magic_page'
make: *** [generate-polls] Error 1

The environment I use is the virtual-box, and vargrant, and the version of python is 2.7, I guess if the version is too low, but I can't update the version because the vagrant can't connect to the internet. Also, I think the CGC has its own environment, so I can't update it by myself.
So I want to know how to solve the problem, and what is the true environment for the challenge to make?
